Gianna is paid 90$ for 5 hours of work

Mathematics
2 answers:
Shkiper50 [21]2 years ago
6 0

You would first have to divide 90 by 5 to see her hourly wage.

She makes $18 an hour.

Divide 60 by 18 to find out how long she would have to work to make $60

She would have to work about 3 1/3 hours, or 3 hours and 20 minutes to make $60.

Hope I helped!

Answer:

3 1/3 hours

Step-by-step explanation:

First we need to find how much she gets paid per hour. We can find this by diving the pay by the hours worked. Let x equal the pay per hour.

90/5=x

We can simplify the fraction by diving both the numerator and denominator by 5

(90/5)(5/5)=x

Do the division

18/1=x

Gianna gets paid 18 dollars per hour.

Now to find how much she needs to work we can divide the money she wants by the pay she gets per hour. Let y be the number of hours she needs to work.

60/18=y

turn into a mixed number

3 1/3=y

She would need to work 3 1/3 hours to make $60

A right triangle has a leg b of length 7 and a hypotenuse of length 11 what is the length of the other leg a?
N76 [4]
A^2 + b^2 = c^2
a^2 + 7^2 = 11^2
49= 121
121 - 49 = 72

Square root(72) = 8.49
or you can just keep the square root symbol with 72 under it

There are 11 students on the tennis team. The coach selects 3 of them to go to atennis clinic. In how many ways can he choose 3
Komok [63]

Answer:

165 ways

Step-by-step explanation:

Selection deals with combination

There are a total of 11 from which 3 are to be selected

        11C3 = 11!/3!(11-3)!

                 = 11!/(3!x8!)

                 =(11x10x9x8!)/(3x2x8!)

                 =11x10x9/6

                 =11x5x3 = 165 ways

Quadratics need help making parabola
timama [110]

Answer:

The equation of the parabola is y = \frac{1}{3}\cdot x^{2}-\frac{4}{3}\cdot x -4, whose real vertex is (x,y) = (2, -5.333), not (x,y) = (2, -5).

Step-by-step explanation:

A parabola is a second order polynomial. By Fundamental Theorem of Algebra we know that a second order polynomial can be formed when three distinct points are known. From statement we have the following information:

(x_{1}, y_{1}) = (-2, 0), (x_{2}, y_{2}) = (6, 0), (x_{3}, y_{3}) = (0, -4)

From definition of second order polynomial and the three points described above, we have the following system of linear equations:

4\cdot a -2\cdot b + c = 0 (1)

36\cdot a + 6\cdot b + c = 0 (2)

c = -4 (3)

The solution of this system is: a = \frac{1}{3}, b = - \frac{4}{3}, c = -4. Hence, the equation of the parabola is y = \frac{1}{3}\cdot x^{2}-\frac{4}{3}\cdot x -4. Lastly, we must check if (x,y) = (2, -5) belongs to the function. If we know that x = 2, then the value of y is:

y = \frac{1}{3}\cdot (2)^{2}-\frac{4}{3}\cdot (2) - 4

y = -5.333

(x,y) = (2, -5) does not belong to the function, the real point is (x,y) = (2, -5.333).
